BOTTLE-CAPSULE AND METHOD OF MAKING SAME.

Specification of Letters Patent.

Patented Oct. it, 191%.

Application filed August 7, 1917. Serial No. 184,810.

To all whom it may concern Be it known that I, GEORGE A. LOGAN, a citizen of the United States, and a resident of the city of New York, county of New York, and State of New York, have invented a new and useful Improvement in Bottle- Capsules and Methods of Making Same, of which the following is a specification.

The purpose of my invention is the production, from tin-foil, sheet-lead, or like material, of compressible bottle capsules, and especially capsules decorated by lithography, printing, die stamping, etc, by a cheaper and more rapid method than any at present employed.

The method permits of decorating the ma terial to be used, by any of these procedures, in quantity, and in the flat condition, in advance of making up the material into capsule form.

According to the invention completely pliable sheet metal material of the character indicated is used, and if the capsules are to be decorated by die stamping, lithography or the like, these operations are first performed in the sheet, after which, or at the same time, the material is out or die-formed into any of the obvious shapes that can be made up into a tube with one end closed. To produce the finished capsule the invention covers the use of controlled heat applied to the capsule material through suitable conveying devices, which unites the edges permanently together so as to produce in eflect a one-plece metal capsule.

The accompanying drawings indicate one of the specific ways of making capsules:

Figure l is a perspective view of a capsule made according to the invention;

Fig. 2 is a side view thereof with a portion in section;

Fig. 3 is a plan view of one of the spread out; and

Fig. 4: is a section through a complementary piece. 7

In the sections the thickness of the material is necessarily exaggerated.

As stated, in the manufacture of decopieces rated foil or sheet-lead capsules under the invention, the material is decorated in the sheet and cut up into suitable pieces, from which the capsules may be formed. I do not limit myself to the precise shapes shown, though these are simple and entirely suitable for my purpose. One of the pieces 1 is a strip having curved long edges and inclined end edges, which can be curved upon itself to form the tapering tubular body of the capsule, the end edges being overlapped. The other piece 2 is a cap-like disk having a flange which may fit either inside or outside of the top of the tube to close the same.

A supply of these or other suitable decorated pieces having been provided, the capsules are made up, either by machinery or by hand, and the lap scams 3 and 4 are autogenously united by the application of heat, or heat and pressure, through suitable irons, or heated pressure or forming deices. To perfect the joint, indentations or perforations 5 may be formed in the overlapped layers, by heated punches, or such localizedheating and deformation may be relied upon solely for the union.

The resulting product is to all intents an integral capsule, but produced much more cheaply than the ordinary article. It will be understood that the seams can be made quite inconspicuous, and need not be by any means as conspicuous as, for purposes of illustration, they appear in the drawing.

What I claim as new is:

1. As a new article of manufacture, a foil or sheet-lead bottle capsule comprising cut shapes with their edges lapped and autogenously heat united.

2. As a new article of manufacture, a foil or sheet-lead bottle capsule comprising cut shapes with their edges lapped and autogenously heat united and indented.

Dated New York, July 25th, 1917.
